inseam;

To all whom it may concern Be it known that we, AXEL C. V. MALM, LEOPOLD RAUH, and CHELSEA R. Anna, citiwhich support the supply of paper, which is usually in the form of rolls.

Various attempts have been made to provide a commercially practical device which could be attached to a typewriting machine to enable a plurality of webs of paper tobe passed about the platen of a typewriter and a correspondingplurality of copies secured upon each operation of the typewriter, by the use of a plurality of plies of ribbon or in any other suitable manner. Some of these machines have been placed upon the market but few, if any of them, have been entirely satisfactory. One of the principal causes of the unsatisfactory character of these devices was the inability to feed the paper supporting device along with the typewriter carriage without interfering with the movement of the latter. One method of feeding the paper supply is to mount the same on a carrier supported on the rear part of the typewriter frame and connected with the typewriter carriage in such a mannerthat any movement imparted to the typewriter carriage will be trans mitted to the carrier. The rolls of paper are necessarily heavy and no matter how easily movable the carrier may be the inertia which must be overcome when movement is imparted to the carrier is very great. As a result the carrier when so connected with the carriage imposes a drag upon the latter which seriously interferes with its opera tion.

The object of the present invention is to overcome these diiiiculties and provide. a paper carrier which will be caused to move along with the typewriter carriage upon each movement of the latter but which will be so connected with the carriage that it Specification of letters Patent.

interfere with the operation thereof.

To this end it is a further object of the invention to provide a connection between the paper 'carrier and the typewriter carwage to cause thewformer to movevwith the latter, and to interpose in said connection at some point between the paper carrier and the carriage a spring whlch will be compressed by the forward movement of the, carriage, thereby permitting the latter to have movement relatively to the paper carrier.

A further. object of the invention is to provide means for so supporting the car rier that little or no strain will be imposed upon the: typewriter frame and the balance of this. frame will not be disturbed; and further, to provide an improved form of track for the carrier.

In the accompanying drawings, Figure l is an end elevation of a device embodying the invention, showing the same attached to a typewriter; Fig. 2- is a top, plan View of the device shown in Fig. l; and Fig. 3 is a sectional, detail view of the track.

In carrying out theinvention we mount at the rear of the typewriter a paper carrier of such a character that it will support the will not impose a drag thereon or otherwise desired number of webs of paper. Usually This carrier is mounted on the track and is arralfiged to move in a path substantially para el with the line of movement of the typewriter carriage. Means are provided for causing both the typewriter carriage and the paper carrier to be advanced upon each operation of the typewriting machine, to permit the typewriter carriage to have movement relatively to the paper carrier and to gradually overcome the inertia of the paper carrier during this-movement of'the typewriter carriage relatively to the paper carrier. V

in the accompanying drawingsis illustrated one form of apparatus embodying this invention and carrying out the operation above described. This particular embodiment of the invention is designed for attachment to a Remington typewriter and in some minor respects is particularly designed for this typewriter, but it-willbe understood that the device can be designed for attachment to various typewriters with-v out in any way modifying the essential features of construction. As here shown a base 1 is arranged in the rear of the typewriter, which is shown at 2, and is so mounted that a large portion of the weight is' carried by the table 3 on which the-typewriter and base are mounted. In this particular attachment the base is provided at its rear edge with depending legs 4 which" rest upon the table top, and the forward part of the base rests upon the rearwardly projecting base of the typewriter. This forward edge of the frame 1s recessed, as shown at 5, to extend partially about the upright members of 'the frame and thus accurately position the base with respect to the frame. Attaching devices 6 are provided to retain the base in engagement with the said frame members.

4 Mounted upon the base 1 is a. paper carrier designed to support a plurality of webs of paper. As has been stated, these webs of paper usually come in the form of rolls and in this particular embodiment of the invention, four webs are utilized. The carrier is, therefore, shown in the form of a frame comprising vertical end members 7 connected one to the other by tie rods 8 and having at their lower ends trucks 9 adapted to travel onthe base 1. Preferably, the base 1 has a track or tracks to cooperate with the trucks of the carrier. In the present instance these tracks comprise parallel bars 10 rigidly secured to the base, spaced some distance apart and provided on their inner faces with V-shaped grooves 11. The trucks 9 of the carriage comprise similar parallel bars which are provided on their outer faces with V-shaped grooves 12 corresponding in size with the grooves 11 of the track. The distance between the outer edges of the truck members 9 is such that they will fit snugly between the track members and when supported at the proper height the grooves of the truck members and of the track members will register. Mounted in the race-way formed by the grooves of thetwo members are hardened steel balls 13. Any suitable number and arrangement of balls may be used but it is preferable to use a small number of balls and to space the same apart by spacing members or rods 14. As here shown a single ball is placed at each end of the track and a group of balls near the center of the track, the group of-balls being spaced away from the end balls, respectively, by spacing rods 14. Thesespacing rods are cylindrical in shape and are of the same diameter as the balls. Consequently, they will engage the walls of the race-way and will exert a small amount of friction thereon. This slight resistance to the movement of the carrier is desirable as it enables the same to be more readily controlled and it is not sufiicient to interfere with the movement of the carrier. Further, this construction of track provides a very steady, non-vibratory support for the carrier. The balls and rods fit snugly m the race-ways'to prevent anyappre'ciable movement of the trucks relatively to the tracks, excepting only the straight longitudinal movement. It will be understood that while this particular form of track has been shown for supporting the carrier this is chosen merely because it is very satis factory in operation and the other features of the invention can be utilized in connection with a track or guideway of any suit able character.

Rolls of paper, which are shown at 15. may be mounted in the frame of the car rier in any suitable manner but, as here shown, they are carried by rods 16 extending through the respective rolls and mounted at their ends in the frame members 7. The webs of paper are drawn from the rolls about suitable guides which may be formed by the tie rods 8 and carried to the typewriter where they are passed about the platen 19, which is mounted on the carriage 20, and properly interleaved with the several plies of inking ribbon or other transfer material. It will be noted that the line of movement of the paper carrier is parallel with the-line of movement of the typewriter carriage and because of the manner of mounting the carrier it is very easily moved in spite of the weight of the four rolls of paper.

In order to advance the paper carrier along with the typewriter carriage there is shown, in the present embodiment of the in- "vention, a connecting member connected at its ends with the paper carrier and type-. Writer carriage, respectively. Interposed in the connection between the typewriter carriage and the paper carrier is a spring which is so arranged that. it will be compressed by the first part of the movement of the typewriter carriage, thus permitting the typewriter carriage to have movement relatively to the paper carrier. As the spring is placed under tension by the movement of the carriage the inertia of the paper carrier is gradually overcome and movement imparted to the-carrier. After the movement of the carriagehas been completed the expansion of the spring will complete the movement of the carrier so that the same is always maintained in a proper position relative to the carriage. When the typewriter is being operated at a normal rate of speed the successive movements of the carriage take place before the expansion of the spring is completed. Consequently, after the move.- ment of the paper carrier has begun it is caused to move forward continuously so long as the typewriter is operated at 21' normal rate of speed. As a result very little resistance is offered to the movement of the typewriter carriage and this resistance in no way interferes with the normal operation of the carriage. This connection between the paper carrier and the carriage may be in various forms but that employed in the present embodiment of the invention comprises a bar 21 connected at its ends with the carriage and with the paper carrier, one of these connections being slidable, and a spring being interposed between the bar and that member with which it is slidably connected. As shown, the bar is pivotally connected at one end to the central. portion of the frame member 7, as shown at 22, and is slidably mounted at its other end upon a pin 23 mounted upon the typewriter carriage and extending longitudinally thereof, and a spring 24 is coiled about the pin between its head and the bar, the bar being arranged, in the present instance, on the right hand side of the machine as the operator faces'it. The bar is preferably slotted to receive the pin 23 and this loose connection permits of pivotal and sliding movements of the bar transversely of the pin, as well as longitudinally thereof. It will be apparent that as the typewriter carriage moves to the left in Fig. 2 it will move away from the bar 21, causing this bar to compress the spring24 against the head of the pin and as the tension of the spring increases it will overcome the inertia of the paper carrier and start the same in motion. In thecase of a single operation of the typewriting machine the carriage will come to a stop before the carrier has completed its movement and this movement will be completed by the inertia which the carrier has acquired, aided by the expansion of the spring. However, in the normal operation of the typewriter the movements of the carriage follow one another so rapidly that there is very little expension of the springbetween the movements and, consequently, the carrier is caused to move forward continuously. After having been once started in motion it is carried along by its inertia and the spring with very little drag upon the typewriter carriage and this, drag is never sufiicient to interfere with the movement of the carriage or to prevent the proper spacing of the letters as the keys are struck.

The operation of the device willbe readily understood from the foregoing description of the several parts thereof and it will be apparent that a very simple, inexpensive device has been produced forcausing the paper carrier to be advanced along with the typewriter carriage without in any way interferin with the operation of the carriage; and urther, that the carrieij' isso mounted that"it"will not impose any material weight upon'the typewriter frame and that it will be very easily moved from one position to another, butalw'ays maintained in perfect balance.

While one embodiment of the invention said paper carrier, wherebylthe movement of'the former will impart movement to the latter, said connection being such as to permit said carriage to have movementrelatively tosaid paper carrier duringthe'norinal operation of said parts.
